JDP_V4_N2_RP5 Anuja Mishra Sharad Mohan Shrivastava Journal on Digital Signal Processing 2322–0368 4 2 34 42 Mode-multiplexing, Multiple Input Multiple Output (MIMO), Digital Signal Processing (DSP), Coherent Next-generation communication evolution towards 4G promises to meet the demands for ubiquitous communication. MIMO technology convolved with Optical fiber has become a mandatory requirement to achieve the goals of future communications. This paper describes the System design methodology for MIMO DSP platform. Software simulations provide flexibility, hence the authors simulate results using a software named “Optiwave's Optisystem”. The authors propose a transmission fiber for mode-division multiplexed transmission with multiple-input multiple-output (MIMO) digital signal processing supporting six spatial and polarisation modes. To increase the transmission capacity of fewmode fiber (FMF) drastically, Wavelength-Division Multiplexing Mode-Division Multiplexing (WDM-MDM), an optical MIMO technique, can be applied. With WDM-MDM, different mode groups, propagating in FMF are used to carry different information. April - June 2016 Copyright © 2016 i-manager publications.
